Abstract: MAGNETIC RECORDING HEAD ARRAY FOR LONGITUDINAL MAGNETIC PRINTING WITH STAGGERED HEAD ARRANGEMENT            AND CLUSTERED WIRING                ABSTRACT            A magnetic recording head array for printing onto a transfer magnetic recording medium which prints magnetic material onto a medium such as paper includes staggered arrays of magnetic print heads. The heads are in diagonally staggered parallel arrays tilted away from the vertical.  Each array in a group of several arrays is also staggered in the vertical direction as well as the longitudinal direction. Preferably, the heads or other bistable elements are wired in clusters with the heads or other elements in the cluster being coupled to the same actuator wires in a half-select type of wiring arrangement.  The difference in the wiring of the elements will reside in the sense of the signal as applied to the elements by means such as reversing the helical winding about a core or the Like.  In the manufacture of the array, the horizontal wiring lines for actuating arrays are in the form of straight lines.

Abstract: ADJUSTABLE TUBULAR WALL STRUCTURE FOR         CONNECTORS AND THE LIKE              Abstract of the Disclosure An adjustable tubular wall structure for tubular connectors, conduiting, containers, and the like, in which the wall structure comprises a tubular body of pleated asymmetrical accordian fold configuration formed from a semi-rigid resiliently flexible material of substantially uniform gauge, in film thickness dimension proportions, that has a central axis extending centrally and longitudinally of same, of which each pleat is defined by a thrust cone wall segment and a Belleville washer wall segment, in which the smaller or narrower ends of the two wall segments are integrally connected to form an annular articulation therebetween and thereabout, and the larger or wider ends of the individual Belleville washer wall segments of each pleat are integrally connected to the larger or wider ends of the thrust cones of the next succeeding pleat, to form an annular articulation therebetween and there-about, with said articulations respectively forming the roots and crowns of the pleating.   The Belleville washer wall segments of each pleat are proportioned to be snap shifted through the articulation of same to the thrust cone of the next adjacent pleat, for shortening or lengthening the tubular body or widening or contracting it, with such articulation including an integral O-ring like protuberance thereabout that controls the axially directed thrust needed for that purpose.  Similar partial snap shifting of the individual Belleville washer wall segments may be effected, for angulating the tubular body, by canting the thrust cone wall segment of a selected pleat sidewise, by way of flecture of the Belleville washer wall segment that is articulated to same in the pleat, to shift a section of same through the articulation between such Belleville washer wall segment and the thrust cone segment of the next adjacent pleat.  In all these relations, namely, extended, shortened and contracted, angled, or any partial positioning of such in same, the tubular body is stable in its adjusted position, both at its ends and lengthwise of same.

Abstract: LOW PRESSURE POOL CLEANER SYSTEM               Abstract of the Disclosure An improved water jet pool cleaner system includes a pool cleaner with a buoyant housing powered about the pool by forward and reverse driving nozzles so dirt and other debris is gathered at the low point on the bottom of the pool by the action of depending cleaner hoses.  Water from the filter pump enters a fluid reservoir from which it flows along parallel flow paths to the forward and reverse driving nozzles, to a turbine, and to the cleaner hoses.  Pressurized water is directed to the forward and reverse nozzles through a rotary valve which is rotated by the drive train con-nected to the turbine.  The parallel flow paths permits water to be provided to the driving nozzles, to the turbine and to the cleaner hoses at pressures substan-tially equal to the fluid reservoir pressure.  The sys-tem uses a flow diverter downstream of the main pool filter to divert the proper amount of water to the cleaner.  Manual and automatic flow diverters and a novel in line filter are also disclosed.

Abstract: Abstract Disclosed is a highly accurate capacitance height gauge which is applied in the presently preferred embodiment in a reticle position detection system for an electron beam lithography apparatus.  The capacitive height gauge circuitry includes a hybrid circuit substrate which carries four measuring capacitor circuits and two reference capacitor circuits.          The driven plates of the four measuring capacitors are disposed on the bottom of the substrate opposite to the object surface to be measured. The driven plates of the two reference capacitors are disposed on the top surface of the substrate under caps which support oppositely disposed grounded capacitor plates at a nominal distance from the driven plates.          The object surface comprises the grounded plate for the four measuring capacitors.  The reference capacitors provide voltage regulation to ensure that a stable signal drives the measuring capacitors.  The reference cap-acitors also set zero points for the measurements from the four measuring capacitors.  These zero points are set at the nominal distance from the measuring capacitor sensors.  The four measuring capacitors provide readings with respect to the object surface to determine the position of the object surface with respect to the nominal zero points.  This information can be used by a suitable control system to manipulate the object surface or tools used to work on the surface in response to the position information as appropriate to the task being performed.

Abstract: ABSTRACT Methods of Assay An electrochemical specific binding assay of a ligand (e.g. antigen, hapten or antibody) wherein at least one of the components is enzyme-labelled, and which includes the step of determining the extent to which the transfer of electrons between the enzyme substrate and an electrode, associated with the substrate reaction, is perturbed by complex formation and/or by controlled external influences.      The electron transfer is aided by electron-transfer mediators which can accept electrons from the enzyme and donate them to the electrode or vice versa (e.g. ferrocene) or by electron-transfer promoters which retain the enzyme in close proximity with the electrode without themselves taking up a formal charge.      The electrochemical apparatus will typically comprise two or three electrodes, including one working electrode onto which components may advantageously be immobilised.      When controlled external influences are employed, they may comprise displacement of the complex formed relative to the unbound enzyme-labelled component.      The use of direct electrochemical measurement of the enzyme label avoids the errors and inconvenience of the known indirect measurement techniques.

Abstract: ABSTRACT OF THE DISCLOSURE       An electronic circuit for converting an AC voltage input signal to a DC voltage output signal utilizes a square wave reference signal for regulating a field-effect transistor to switch on the input signal for a half period, and to switch off the input signal for a half period, whereby ripple current flows through a first filter coupled to the transistor for only a half period, with a steady discharge current through the first filter for the other half period, thereby reducing ripple.  A second filter coupled to the first filter and an operational amplifier further diminishes ripple.

Abstract: RCA 80,748 ABSTRACT A color television receiver with luminance and chrominance signal channels includes an automatic kinescope beam current limiter, an automatic white level drive control network, and an automatic black level bias control network.  A switching network is timed to operate such that a control signal developed by the beam current limiter is coupled to the luminance channel during normal picture intervals, but is decoupled from the luminance channel during both white level drive control intervals and black level bias control intervals.  The beam limiter control signal is continuously coupled to the chrominance channel, independent of the operation of the switching network, to permit chrominance output bias offset errors produced by beam limiter action to be sensed and compensated for by the automatic bias control network.
